V17 Modbo modchip installation diagram

The last PlayStation 2 models sold in Japan used the V17 board revision. They were also sold in many PAL markets, but not in North America. Matching console model numbers and board numbers are listed below.

You can find the model number on the sticker on the bottom of the console, and the board number is printed on the PS2 main board if you take apart your console. Note that there can be multiple board numbers within a specific model number.

  • NTSC-J (Japan):
    • SCPH-90000 CB (GH-070-42)
  • PAL
    • SCPH-90002 (GH-070-42)
    • SCPH-90003 (GH-070-42)
    • SCPH-90004 (GH-070-42)
    • SCPH-90005 (GH-070-42)
    • SCPH-90008 (GH-070-42)
    • SCPH-90009 (GH-070-42)
    • SCPH-90010 (GH-070-42)

Note that there are multiple versions of the Modbo modchips available, but the installation diagrams are all the same. Some example versions are Modbo 3.0, Modbo 4.0, Modbo 5.0, and Modbo 750.

Installation tips

Here are some tips I have for you when you are soldering your chip into a V17.

  • Using 30 AWG solid core wire works well for most of the points.
  • Use some thicker wire for the 5V and ground wires.
  • Using thinner wire for the (A), B, G, H, and I pins makes things a lot easier. 36 AWG enamel wire along with some flux and slightly pre tinning the pins on the chip seems to work well for me.
  • Make sure wherever you are putting your chip won’t cause any issues when putting the system back together, PS2 slims fit together very tightly.

Hey, do you know which pin is related to restart modchip after game was booted? Mine won’t restart with PS2, but would do with PSone games.

I have got a SPS2 model №90004a PAL. And it has a board GH-070-12.(not GH-070-42). What kind of installations diagram would you recommend?
